WHEELED CARRIAGE FOR GUNS HAVING A LARGE HORIZONTAL ANGLE OF FIRE.

Specification of Letters ilatent.

Patented Sept. 16, 1919.

Application filed February 14, 1918. Serial No. 217,189.

To all whom it may concern:

Be it known that I, EUGENE SCHNEIDER, a citizen of the French Republic, and a resident of Le Creuzot, Saone-et-Loire, France, have invented a new and. useful Improvement in Wheeled Carriages for Guns Having a Large Horizontal Angle of Fire, which invention is fully set forth in the following specification.

This invention has for its object to provide an improved wheeled gun carriage having a large angle of horizontal fire.

The improved gun carriage is characterized essentially by the combination of anchored plates for supporting the wheels, with a tensile member or tie of constant length but deformable, located between the said plates and the carriage trail. This tie may be pivoted at its ends at two fixed points on the said plates, and bears at a variable intermediate point upon a guiding device carried by or formed on the carriage trail. As the result of this combination, if the carriage is constructed in such a manner that the trall alone or the entity comprising the trail and the wheeled axle, is able to turn on a real or imaginary pivot equidistant from the points of attachment of the deformable tie, the gun carriage will turn about the point of intersection of two vector radii of an arc of an ellipse, having for its foci the points of attachment of the tie to the plates, said are by reason of the dimensions of the gun carriage coinciding practically with the arc of a circle described by the trail around the centeron which it turns. In all positions the apex of the deformable tie and the two points of attachment of the latter will constitute a' triangle for maintaining the stabilityof the gun carriage during firing. The changes in position will not require any modification of the anchorage and can be produced by merely displacing the carriage trail. The deformable tie of constant length, instead of bein attached at its ends to two fixed points 0% the anchoring plates and guidedon the trail, may inversely be attached at its ends to the trail and be guided on members located at the foci of the ellipse formed onvv the plates...

Several constructional embodiments of thi invention are illustrated in the accompanying drawings in which:

Figures 1 and 2 are respectively a side elevation partly in section and a plan of one embodiment of the invention.

Fig. 3 is a diagram showing in full lines the gun carriage in mid position for training the gun, and also showing respectively in dash and dot lines and dotted lines the same gun carriage in two extreme positions symmetrical to the said mid position.

Figs. 4 and 5 are respectively a side elevation partly in section and a plan of another embodiment.

Fig. 6 is a part horizontal section on the line VIVI of Fig. 4.

Fig. 7 is a plan of a further embodiment of the invention.

Fig. 8 is a plan of another embodiment of the invention, and

Fig. 9 is a diagram illustrating a particular manner of applying any one of the embodiments above referred to.

In all these figures, A is the gun carriage axle, B B are the wheels and G is'the trail of awheeled carriage of any known type.

' The gun carriage in the firing position rests with its wheels on plates D, D, which are anchored to the ground by known means, for instance by means of stakesE.

In all these embodiments the gun carriage is constructed in such a manner that the trail C is capable of turning on a center 0. The wheeled axle A, BB may move with the trail around said center or remain stationary. In the latter case the trail is jointed to the axle by means of a vertical pivot.

' According to this invention the carriage comprises a deformable tie of constant length located between the carriage trail and two fixed points F of the plates, said points In that construction two stays each consisting of two sections H, H connected together by a turn-buckle h, are jointed at their section H to the fixed point F of the corresponding plate, while they are each connected at their section H to one of the, ends a pitch chain I passing over a pinion G pivoted'on the trail spade.-

In the embodiment shown in Figs. 1 and 2,

in the diagram of Fig. 3 (position I), then bymofving the gung'trail, the whole of the wheeled .axle and trail can be moved into the extreme positions II and'III (Fig. 3) or. into. any other intermediate position.

- In practice, the arc of, the ellipse having its foci at the points F, F, which is described in those movementsby the supportingpoint 9-. of the deformable tie upon the member G, will substantially coincide with an arc of a circle described from the point Oas center with the radius Gee-g:

Thee means for, operating the turning movement of the gun carriage may comprise for instance=the parts shown in Figs. 1. and 2. The pinion G on which the deformable member of constant, length (the pitch chain I) is.'-.journaled inthe guntrail, is formed on the upper edgev of its hub with a series of projectionsaG alternating with recesses G ,In the pinion there isslidably mounted apin J formed with. a square portion J guided in the trail, and a block J 2 carrying a :pinK on which is pivoted intermediately ofits lengtha training lever L, One end of this leverishpivoted at L to the-carriage trail. A shoulderM on the pin J is formed on. its underside with projections M engagingfin the rest position in the recesses G Solong as the projections M are engaged in the'recesses G ,,the pinion G is locked in position.-

If on the contrary by raising the lever L, the projections M are moved'out ofcthe recesses G the pinion G is able to revolve freely around the pin J, when by means of the training lever L the whole of thetrail and wheeled gun carriage is turned in the horizontal plane. T

The corrections in the training movement may be effected by any known means, for instance by slidin the trail C along the axle A which is suita- 1y curved for this pur- .ose. I P In the'embodiment shown in Figs. 4: and 5, theanchgring plates D, D comprise each along its major axis, a channel D in which the; corresponding Wheel is engaged, so that s emme the wheeled axle remains stationary during the training movements and the trail alone is turned horizontally around a vertical pivotN, N by means of which it is jointed to the axle A.

For effecting considerable changes of trainingthegun maybe turned as in the preceding examples, by means of the rear training lever L. For small corrections of the training, it may'comprise the mechanism shown in Figs. 4 and 6.

The pinion G is mounted on a square portion J ofa pin J5, J, which is capable of being lifted vertically by means of the block J 2 by the training lever L. The upper portion J ofthe pin J J is tubular and is capable of turning on a stud 7' formed under the block J On this tubular portion J there is mounted a helical pinion P formed on its hub with projections 39 with which there can" be engaged corresponding projections formed on the underside of a collar of the pin J J. When this engagement is produced by depressing the training lever L, the carriage trail maybe turned for the purpose of correcting the training, by; actuating the pinion P by means of gearlng such as Q,R-S-StT.

v III 'QIdBI to prevent any forward dis placement of the wheels B during firing, wedging blocks U may be located in a known manner on the anchoring plates.

The deformable tie of constant length that connects the plates for the wheels to the-carriage trail, instead of being fixed to the two points of those plates constituting the foci of the ellipse while the said tie is movable on the carriage trail, may inversely befixed to the trail and be movable on de-' vices located at the two fixed points of the plates.

ciple shown in plan in Fig. ,7, guiding dey v ces suchjas rollers F? for guiding anona r1g1d portion H of the deformable tie, of constant length, are mounted on vertical axle pins f, f, at the two fixed pointsF, F of the plates D for the wheels. H maybe a cable the two ends if, 7&2 of whichl'consist of hooks engaging in eyes of the rigid sections H of thetie. The sections H mav be hooked to fixed attachments k of the trail.

In the embodiment shown inlFig. 8, the non-rigid section H? of thedeformabletie consists of a pitch chain movingover. in-, irms F mounted on axle pins f at xed pointsof a continuous circular wheel plate 0 3;; The section H is further guided on a 1n1on V mounted on an axle pin "0 proecting from the plate D at its center 0. f

It will be understood that the turning movements of the gun for changing the training may be effected by actuating the pinion V or one of the pinions F .As shown in the diagram of Fig. 9, there may be arranged at suitable points of a complete circumference on a wheel plate D, a plurality of pairs of foci F, F constituting as many points of jointing or guidance for the deformable tie of constant length. By varying the points of attachment of the tie, it is possible to vary all around the horizon the sector in which the gun carriage can be turned by pivoting around the center 0 of the plate, without changing the attachments or the guides.

The carriage trail may for example as shown in Fig. 1, be provided with attaching members W, for fixing the ends of the deformable tie during transport.

.What I claim is 1. In combination, a wheeled gun carriage having a trail provided at the end resting on the ground with a guide pulley, anchored shoe plates for supporting the carriage wheels and a horizontally arranged tie having its ends secured to said plates and having a deformable portion running. over said pulley the axis of; which remains perpendicular to the plane containing both branches of the tie for all angular firing positions of the trail.
